The red dots indicate stations reporting exceedances of
the 2010 annual target value (25 μg/m3) plus at least
5 μg/m3.
The dark orange dots indicate stations reporting
exceedances of the 2010 annual target value
(25 μg/m3), as set out in the Air Quality Directive.
The orange dots indicate stations reporting
exceedances of the 2020 indicative annual limit value
(20 μg/m3), as set out in the Air Quality Directive.
The pale green dots indicate stations reporting
exceedances of the WHO air quality guideline for PM2.5
of less than 10 μg/m3 but not in exceedance of target
or limit values for PM2.5 as set out in the Air Quality
Directive.
The dark green dots indicate stations reporting
concentrations below the WHO air quality guideline for
PM2.5 and implicitly below the target and limit values for
PM2.5 as set out in the Air Quality Directive

The red dots indicate stations reporting exceedances of
the 2005 annual limit value (40 μg/m3), as set out in
the Air Quality Directive.
The orange dots indicate stations reporting
exceedances of a statistically derived level (31 μg/m3)
corresponding to the 24–hour limit value, as set out in
the Air Quality Directive.
The pale green dots indicate stations reporting
exceedances of the WHO air quality guideline for PM10
of less than 20 μg/m3 but not in exceedance of limit
values as set out in the Air Quality Directive.
The dark green dots indicate stations reporting
concentrations below the WHO air quality guideline for
PM10 and implicitly below the limit values as set out in
the Air Quality Directive.

Black carbon is an air pollutant which harms human health and can contribute to climate change – so cutting emissions may have many benefits. The European Environment Agency (EEA) has published a report on the measurement of black carbon in the air.

Carbon capture and storage (CCS) involves capturing carbon dioxide released by power stations and other industrial sources, and burying it deep underground. But in addition to keeping an important greenhouse gas (GHG) out of the atmosphere, this technology will lead to benefits and trade-offs for air pollution. A new report from the European Environment Agency (EEA) describes the effects that CCS may have on emissions of some key air pollutants.
